Description

The ridden by two-person three-wheel vehicle

The utility model is a kind of ridden by two-person three-wheel vehicle.

Samll cities and towns in a lot, in the rural area, manual tricycle still is the main transportation means of ordinary people, and consumption is also quite big, and this situation is also gone down long-term existence.A problem of present manual tricycle is that people is by bike pedaled motionless when car bears a heavy burden upward slope, the walking go-cart of need getting off, and perhaps another people is pushing away from behind just and can advance.This mode is not only required great effort but also time-consuming, and go-cart still by bike people is all very tired, and the people of go-cart in the back particularly just can take a breath when only shifting slope onto, pedals to get on the bus after car stops again and advances, and is very inconvenient, also can cause danger sometimes.

The purpose of this utility model be exactly in the time of will proposing a kind of the upward slope without walking push away, can two people with ride, laborsaving ridden by two-person three-wheel vehicle quick and easy to use, to overcome the deficiencies in the prior art.

This ridden by two-person three-wheel vehicle that the utility model proposes, it has front-wheel, trailing wheel, brake gear, railway carriage and vehicle frame, it is characterized in that having on the vehicle frame two seat cushions side by side, respectively establishing one under the seat cushion flies greatly and step, have on the axletree of rear wheel two with fly greatly correspondingly to fly for a short time, have chain to connect transmission between large and small flying, on the two seat cushion front vehicle frames handle is housed respectively, the connecting rod that has the direction done to regulate usefulness between one of them and front fork links.

Two on the hind axle fly symmetric offset spread for a short time and install.

Vehicle frame is made of keel bar, two side levers and digonal link, keel bar front end and front fork axle bed are fixed, rear end and railway carriage are connected as a single entity, its preceding half section is brace, second half section is straight bar, the both sides rod rear end respectively has the supporting of two montants fixing, front end with and front fork axle bed bonded assembly cross bar fix, digonal link is fixed as one keel bar, side lever and hard bar.

Brake gear is consistent with existing three-wheel vehicle.

There is not handlebar on the front fork.

The utility model on available man-power three-wheel vehicle basis in vehicle frame keel bar bilateral symmetry set up side lever, seat cushion, fly greatly and step, cancellation front fork handlebar, change by a sidecar handle by the connecting rod steer direction, solved the problem that three-wheel vehicle can not two people drives side by side simultaneously dexterously, with the same bicycle of riding of front and back two people, three-wheel vehicle is compared, shortened vehicle body, saved material, operation also becomes easier, structure of the present utility model in addition is also compact especially, and the same mass distribution of riding of two people is even, and center of gravity changes little, no matter empty wagons loaded vehicle person can both smooth running, and people drives also can safety traffic.
